用简便方法计算125x26x4x8x5x20x25

原式=125*8*4*25*5*20*26=1000*100*100*26=260000000

简便计算过程方法如下解:125*26*4*8*5*20*25=(125*8)*(5*20)*(4*25)*26=1000*100*100*26=100000*100*26=10000000*26=260000000

=(125*4)*(25*4) =500*100 =50000

24x2x125x25=3*8*2*125*25=8*125*2*25*3=1000*50*3=150000

125x25x4x4用简便计算=(125x4)x(25x4)=500x100=50000

脱式计算过程方法如下解:125*26*4*8*5*20*25=(125*8)*(5*20)*(4*25)*26=1000*100*100*26=10000000*26=260000000

125174x825x5x20=(125x8)x(25x4)x(5x20)x17=1000x100x100x17=170000000

125X3X25 = 125X3X5 X 5 = 625 X 15 = 9375

56x25x4x125=7x8x125x25x4=7x(8x125)x(25x4)=7x1000x100=700000 希望帮到你 望采纳 谢谢 加油

【最佳解答】把32分成4乘8,8和125乘得1000,4和25乘,得100,然后100乘1000,100000
